US Congress denied details of interrogation probe

United States Attorney-General Michael Mukasey has refused to give Congress details of the government's investigation into why the CIA destroyed videotapes showing suspected terrorists being questioned.

Mr Mukasey said supplying the details might suggest that political pressure could influence law enforcement decisions.

The videotapes apparently showed controversial techniques such as waterboarding, which simulates drowning.

The CIA denies torture.

Meanwhile, Republican Senators have blocked a bill restricting the interrogation methods that the CIA can use.
